One way to investigate the amount of progress, in the worldwide adoption of torture preventive measures, that APT has made through the years can be to show how many States ratified how many indicators each year since 1984 (gif on the right).

The indicators are 8 in total and vary from the prohibition of torture in the constitution to the ratification of the UN Convention against torture, for example. Criminalisation of torture under domestic law is the indicator that some States have only partially ratified.

So, starting with 1984, we have 32 States that ratified 1 indicator and 1 that ratified 2.
Today, after 40 years, 102 States have ratified between 3 and 6 for instance, for a grand total of 934 indicators ratified.

If we want to have a look at each indicator instead, the graph below displays the number of States that had one ratified at a specific point in time, communicating well the increment throughout the years.

We can change the indicator in exam via the dropdown menu.
Furthermore, hovering over the bars will show the total number of States per year.
